This text fixes the conditions under which structural construction is not admitted. It does not introduce a model or define a system, but rejects the admissibility of assignment, mapping, and set-theoretic construction as structural operations. Assignment is not admitted, as it fixes terms as independent entities. What appears under relational constraint does not constitute a term and is not admitted as an independently established entity. Mapping is not admitted as an operation; constraint is fixed without transformation, generation, or transport. Set-theoretic construction is not admitted; what appears under constraint does not constitute a set. Within this framework, what appears as loci does not admit constructive expression and does not form independent terms. Retention is fixed as a structural condition internal to difference-configuration. Localization is fixed without constructing a domain, coordinate system, or index. No construction is performed. No object is generated. Structure is not constructed but fixed.
